[amdgpu] Monitor does not wake from sleep unless power cycled

[Tiago Matias]

Hello,

I have a persistent issue where my freshly installed Ubuntu sleeps the monitor after booting.

The solution is to turn the monitor off and on again. After turning it on the login screen is displayed.

Note that when the screen is off even the combination CTRL+ALT+F2 to switch to a console TTY will not work.

Rarely the system will boot to the login sleep without the screen going to sleep.

There is the following message on dmesg:

[ 63.052273] amdgpu 0000:0a:00.0: [drm] *ERROR* mstb 00000000d9e48d98 port 1: DPCD read on addr 0x4b0 for 1 bytes NAKed

Using the default Ubuntu graphical drivers.

I would also like to add that this issue also manifests when the display goes to sleep.

Moving the mouse or touching the keyboard (which should wake the display up) produces no effect and requires turning the monitor off and on again.

Looks like the same kernel message as in bug 1970495
